Scrubber



Patentecl Oct. 6, 1942' I UNITED-STATE .5 i PATE TY'O FFIoE Y Allis-Chaim ers Manufacturing Company, Milwaukee, Wis, a corporation otDelaware v Application Mathias, 1941, $erlal in. 385,595 *4 Claims. (01, 209-6) This invention relates to a scrubber of the vibrating type-for removing adherent impurities from ore, gravel, etc. -An' object of this invention vibrating scrubber with transverse scrubbing pockets having bodies extending longitudinally of said pockets and loosely retained therein to aid in the scrubbing action within the pockets.

- Other objects will become-apparent from the is to provide a ducted to any desired parts ot the deck by means of distributing pipes 25. Pipes 22 may have their ends plugged to prevent entry of material into I the pipes.

tially vertical sides 21 and inclined sides 28. It

has been found that pockets of this shape are conducive to thorough scrubbing action of the material passing therethrough, particularly when following description taken in connection with 1 the direction of vibration is generally parallel to the drawing, wherein:

- tion or reciprocation of deck 10 in the direction indicated by arrows I2. The deck carries a screen section and a plurality of pockets I6, l1, l8, l9 and "which extend transversely of the screen from side to side thereof. Material is fedto the deck by means of chute l4 and, due to the vibration of the deck. is caused to passlongi tudinally of the deck from the feed end to the discharge end. During its passage over the deck,

the material being treated is screened and washed and impurities adhering to the material are removed by the scrubbing action taking place in 3 the pockets.

It has been found that the scrubbing action in the pockets is much more thorough when longitudinal bodies, such as hollow pipes 22, are loosely retained within the pockets. These longitudinal bodies vibrate with the deck and material and are caused to rotate by friction between bodies 22 and the ore or other material being treated.- The combined impact'and frictional 7 contact between the material and bodies 22, together with the changed spacial characteristics of thescrubbing pockets, greatly increases the scrubbing capacity of the scrubber.

"In order to retain bodies 22 from moving toward the discharge end with the material brackets 23 are provided on the sides of the deckl0. These brackets are preferably provided with curved portions 24 to prevent bodies 22 from'being thrown upwardly out of the kets during the operation of thescrubber. Water is conthe planes of the inclined pocket walls. Brackets 23 are so arranged as to retain bodies 22 loosely adjacent vertical walls 21, where the pockets have their greatest depth. It has been found in 15 operation that dams, previously used to prevent flow of material across the surface of the deck and by-passing the pockets, are unnecessary when bodies 22 are utilized. This results in increasing the capacity of the scrubber. While 0 only one pipe 22 has been shown in each pocket,

it is clear that two or even more pipes may be used.- Members 22 'may be hollow pipes as shown or solid cylinders or any other suitable bodies,

' and need not .be round in cross-section, They- 25 should be loosely retained within the pockets,

and should take up appreciable space therein.

It is claimed and desired to secureby Letters 1 Patent: J

1. In a vibrated scrubbing deck having sides, a

39 feed end and a discharge end, means for vibrating said deck in a plane parallel to said sides, a I plurality of pockets arranged in said deck and extending from side to side thereof, said pockets comprising planar walls arranged at an acute 5 angle to each other, longitudinal members loosely retained within said pockets and extending substantially the full length of said pockets, and .means carried by said sides and extending inward therefrom for retaining said members adjacent one of said planar walls .of said pockets 5 deck, each of. saidpockets comprising a vertical wall depending from said deck and an inclined wall depending from said deck and connected to the lower end of said vertical wall, bodies extending substantially across the entire length of said pockets, and means for loosely retaining said bodies for vibration adjacent said vertical walls I of said pockets.

3. A scrubber comprising a substantially horizontal deck, a plurality of pockets arranged transversely of said deck, said pockets comprisranged in said deck, each of said pockets com-.

prising two planar walls depending from said deck at an; acute angle to each other and joined at their lower ends by a rounded bottom, a plurality of rods extending throughout substantially the full lengths of said pockets, means for loosely retaining each .of said rods adjacent one of said planar walls of said pockets, said deck comprising a substantially horizontal screen section extending between atleast two of said pockets and connecting the upper ends of adjacent walls of said two pockets.
